110V 5CFM Vacuum Pump |
 |
| Description: |
| The rotary vane vacuum pump is the basic
equipment used to extract gas from the airtight container. It can be
used alone or as the pre-pumping pump of booster pump, diffusion pump,
molecular pump, maintenance pump and titanium pump. It can be used for
the manufacture of electric vacuum devices, vacuum welding, printing,
plastic absorption, refrigeration equipment repair and instrument
matching. The dual-stage vacuum pump is small in
size and light in weight, and has a large oil window for easy
observation of oil volume even when adding oil. The oil mist catcher has
the advantages of five-layer filtration, effective prevention of oil
smoke splashing and noise reduction. |

| Operating Instruction: |
1. Check the oil level and fill the oil to the center of
the oil pointer when the pump is stopped. If it is too low, it will not
seal the exhaust valve and affect the vacuum degree. If it is too high,
it may cause fuel injection during atmospheric starting. It is normal
for the oil level to rise during operation. Oil is added from the oil
filling hole, and the screw plug shall be screwed on after filling. The
oil should be filtered to prevent sundries from entering and blocking
the oil hole.
2. The pump can be started at one time under atmospheric or any vacuum.
If a solenoid valve is installed at the pump port, it should act
simultaneously with the pump.
3. When the ambient temperature is too high, the temperature of the oil
will increase, the viscosity will decrease, and the saturated vapor
pressure will increase, which will cause the limit vacuum to decrease,
especially the total pressure measured by the thermocouple. If the
ventilation and heat dissipation are strengthened or the pump oil
performance is improved, the limit vacuum can be improved.
4. Check the limit vacuum of the pump based on the compressed mercury
vacuum gauge. If the vacuum gauge has been fully pre-pumped and
calibrated, the pump temperature is stable, the pump port is directly
connected with the gauge, and the limit vacuum will be reached within 30
minutes of operation. The value measured by the total pressure gauge is
related to the pump oil, vacuum gauge and gauge error, sometimes the
error can be even large, and can only be used as a reference.
5. If the relative temperature is high, or the extracted gas contains
more condensable steam, open the gas ballast valve after connecting the
extracted container, and close the gas ballast valve after 20-40 minutes
of operation. Before stopping the pump, the gas ballast valve can be
opened for 30 minutes without load to extend the service life of the
pump oil.
6. Oil selection: the viscosity of the pump oil affects the starting
power and the limit vacuum of the pump. When the viscosity is high, it
is beneficial to the vacuum degree, while the starting power is higher.
The saturated vapor pressure of oil at pump temperature will affect the
ultimate total pressure of the pump, the lower the better. The viscosity
of high-speed vacuum pump oil and 3 # diffusion pump oil is higher than
that of 1 # vacuum pump oil, and the saturated vapor pressure is lower
than that of 1 # vacuum pump oil, but the price of 3 # diffusion pump
oil is higher. The specific oil to be selected can be selected according
to the above introduction and the specific use requirements.
(1) In general, the high-speed vacuum pump oil made in Shanghai should
be used where the total pressure is expected to be more than 6X10-2.
Small pumps below 4L/s can also be replaced by 1 # vacuum pump, and
direct-connected pumps above 8L/s can be replaced by 3 # diffusion pump.
(2) If the requirements for vacuum degree are not high, and the oil is
polluted and replaced frequently, and the vacuum pump oil supply is
difficult, No. 50 machine oil can be used instead.
(3) If the ambient temperature is low, it is difficult to start, and the
limit vacuum requirement is not high, the real pump oil or mechanical
oil with lower viscosity can be used. |
